I currently have a 2012 550i with Dinan stage 3, Active Autowerke custom exhaust and soon to be installed Dinan intercoolers and Big break kit with stage 4 dinan flash.

I love the car but today my wife drove it and loved it so much that asked if she can have it. This gives me the opportunity to jump into the M5.

Do you guys think is worth the change? I have not been able to really drive an M5 since the dealer doesn't let me test drive it at high speeds so I don't know if the difference is going to be worth it..

What do you guys think of the M5 is it worth the $110k?

Other options I can now consider:
Used Audi R8 V8
911 turbo 997.2
Audi S7

Things to consider:

My wife travels to NY and Europe very often so I get to drive whatever car she owns...

I can wait for the M5 to depreciate a bit before making the jump but if the car is really as amazing as they say I don't mind and I can go with European delivery and make a vacation out of it...

Annoying how some SA's don't allow you to actually feel for the car. I test drove an e63 and the SA let me rip it to 130! LOL, there are several M5 miami owners on here, I am sure one of them would be happy to take you for a drive and give you a feel for it. Also note, dealer cars aren't even broken in yet so you really can't get a good feel for it in general.

Mercedes E63 - Hate the current e63 hoping the 2014 is much nicer, the current mercedes models have nothing on our BMW's its amazing how much better the BMW is to the Mercedes, simple things like the door locks in the mercedes seem so cheap, the interior is not very inviting and not alot of great options)

BMW M5 - Really love this car but honestly just comparing it to my 550 is just not much difference, the 550 drives and handles amazing so not sure is going to be worth it. Also the problem is that we will be doing European delivery and with so many M5's in stock in the states I feel like I wont be getting a good deal if I buy it with european delivery.

Audi S7 - Have not seen it yet but I do not like the back, it looks like the car is constipated

Why are there so little options!!!! I am willing to go up to $125k and I cant find anything i like other than the BMW... I hate this

While I agree that the M5 is a completely different car than the 550i (yes..in every way. I love that quote about every 550i driver wishing he was driving an M5), if I were I your shoes I would give the wife my M5 and buy a sporty little coupe. 997TT for sure. Saw a black one at a dealer while I was driving my M5 to the tuner yesterday and was already thinking...lol!

I've thought of this as well problem is that we are planning to have a baby soon and not sure if having the small 911 is a smart idea.. This will be our first kid so I don't have lots of experience...

Yup. That is why I bought the M5 and not the M6. Have an 8 yr old and a 5 month old. Car seats (and hockey gear) become a very big part of your buying decisions. CONGRATS on the decision! Kids are worth EVERY sacrifice. My 8 year old knows more about M5s than most of the salespeople at the dealer. They all get a very big kick out of him. The other day I look at my wife and say "where's Gavin?" He yells from inside a MCB M5 on the showroom "over here in the F10 daddy!". I was sitting with our sales guy/buddy and I said "don't say F10 buddy. You will confuse him. Say "pretty blue car". All the sales guys laughed. All of his teachers and kids at school get plenty of lessons on cars too. Recently he says "we are just alike Daddy, we like cars, guns and hotties!" THAT is when having kids is such a blast!

Now get the Porsche before it's too late! TRUST ME ON THIS! hahahahahaha

The way the M5 takes a corner is night and day. The car stays dead flat around corners, and when you put the gas down midway, the limited slip diff at the back makes a huge difference in getting the power down fast. The diff, the steering, and the chassis stiffness are all differences between the 550i and the M5.
